BACKGROUND

Sensors comprising electrodes, a track and an electrical connector areused extensively in the assessment of clinical condition, for example,without limitation, in the monitoring of a cardiac condition. Theelectrodes are placed in contact with the skin of an individual,including, without limitation, a human body and the electricalphysiological signals which result are examined. The physiologicalsignals themselves are transported through an electrically conductivetrack to an electrical connector which couples with an electronicinstrument for receiving, collecting, storing, processing and/ortransmitting the data generated by a sensor. Such data may be used tomonitor and/or evaluate the health and/or physical state of a wearer.

While using a sensor can provide an accurate measurement of a signal,there are several factors that can affect the signal quality, including,without limitation, stability, noise and/or sensibility. Theselimitations are due, at least in part, to factors such as motion. Thiscan be exacerbated when a sensor is included in a garment. In such asituation, the electrode and track of a sensor need to be integrated ina garment in a minimally invasive manner that allows, for example,without limitation, flexiblity, and comfort to an individual's body,including in movement and be resistant to degredation due to repeatedwashing. At the same time, a sensor must also be capable of measuring asignal accurately.

To reduce background noise, one solution has been to attach a sensor tothe skin with an adhesive. An issue with such an arrangement has beenthe lack of comfort and the inability to reuse the sensor as it can onlybe applied once to an individual at which point it is usually disposed.Therefore, there is a need for a sensor that is integrated in a fabric,such as, without limitation, a garment, wherein an adhesive iseliminated and is replaced with a sensor that is applied to the skin ofan individual using the fabric's pressure to the body. One way in whichpressure can be created is to make a sensor flexible, elastic and withimproved adhesion properties, but avoiding adhesive elements, so that itcan adapt to every different type of body. This includes making thetrack flexible and elastic and the electrode flexible and with improvedanti-slip property such that every movement made by an individual's bodywill be translated into an electrode and a track keeping it in place,while an individual is in motion while retaining the fidelity of thesignal. To accomplish this result, a track can be constructed of aflexible and elastic conductive material, for example, withoutlimitation, a silicone conductive rubber.

A problem facing the developers of advanced electronic textiles is howto interconnect electrical components and electronic devices with eachother and with electrical connectors via electrically conductive tracksprovided on the fabric substrate of an electronic garment. It is knownin the field of electronic fabrics, when the substrate is a wearable,elastic and flexible garment, the integration of rigid elements createsa weakness and frequently the rigid element will break the garment whenit is stretched.

With regard to a silicone conductive rubber, one issue related to theuse of this material in a garment is that the garment can be damagedduring the curing process. This has limited the use of siliconeconductive rubber as a means to connect an electrode to an electronicconnector until a means to cure it on a fabric at room. Other drawbacksof a sensor where the track is made by a semi-conductive elasticmaterial include having a mechanically weak linkage between the trackand an electrical connector when the fabric is stretched. One result isthat the fabric can tear after suffering a physical stress.

The development of a sensor and a garment comprising a sensor withflexibility and elasticity which allows recording physiological signals,especially in movement, with improved adhesion properties but avoidingadhesive elements which produce skin irritations is of great interest.In addition, the development of an improved silicone conductive elastictrack and electrical connector assembly in wearable fabric and a methodto cure a silicone conductive rubber at room temperature, including,without limitation, on a garment, is of great interest.

SUMMARY

The present invention solves the problems described above by providing asensor comprising, in at least one embodiment an electrode, a track andan electrical connector, wherein, the track is comprising anelectrically conductive flexible and elastic material that comprises anelectrically conductive material that is non-contiguous that whenstretched is able to transmit an electrical signal from an electrode toan electrical connector and from an electrical connector to anelectrode.

FIGS.20, 21 and 24 depict an elastic semi-conductive track and flexibleconductive support base assembly wherein, each end of track 20 a and20′a are treading on two different flexible conductive support bases 20and 20′.

As depicted in FIGS. 20, 21, 22 and 24, a conductive support base 18 isa flexible and conductive textile comprising conductive andnon-conductive fibres, having at least one of its ends 20 a, the endwhich is treaded by the track, round shaped, being in an embodiment, andwithout limitation, a teardrop-like shape as depicted in FIG. 22. Inanother embodiment, the shape and dimension of a track may vary and itis not limited by the manufacturing process of the fabric substrate.

In an embodiment, a conductive support base has a teardrop-like shape,wherein a connection edging between the support base and a track has ashaped end, including, without limitation, a round shaped end that can,without limitation, improve the mechanical resistance to stretching,minimizing or substantially avoiding tearing the joints when the trackis stretched, twisted, folded and/or squeezed while used. Furthermore,the circuit design is simplified since the support base can be guided tothe track direction and vice versa.

This results in the mechanical properties of a joint betweenan elastic and a rigid element being low as the assembly suffersmechanical stress. When the assembly is integrated into a textile, themechanical properties of the joints between the different materials arecrucial to obtain a proper electrical circuit.

In an embodiment, a track is integrated into a fabric and partially intoan at least one round shaped end of a conductive support base byanchoring the flexible material, including, without limitation, siliconewith the structure of the fibers of the textile.

EXAMPLES Example 1

In this experiment the following garments were used: ZEPHYR™ HxM (madeby Zephyr Technology Corporation) (I), Polar TEAM² (made by PolarElectro, OY.) (II), NUMETREX® Cardio-Shirt (made by Textronics, Inc.)(Ill) and a shirt of the invention (IV), wherein the shirt of theinvention included a track and the electrode that were made ofconductive fabric and the electrode area has the orifices filled withsilicone rubber. The NUMETREX® Cardio-Shirt is a shirt with textileelectrodes knitted into the fabric. The ZEPHYR™ HxM strap and PolarTEAM² strap are straps with textile electrodes. The ZEPHYR™ HxM strapincludes an electrode and a resilient compressible filler providedbetween the garment and the electrode such that, in use, the electrodeis held substantially in place against the skin when the garment movesrelative to the user's skin. The Polar TEAM² strap includes a contactlayer including conductive fibres, and a moisture layer for retainingmoisture on top of the contact layer.

The test protocol was divided into different levels of physicalexigency: resting, daily activity and strong physical activity. Eachtest subject was monitored with a device compatible with all the strapsand shirts tested. The exercises of the protocol were defined asfollowing:

-   -   (I) Resting (A): the subject remained in a lying down position        on a table for 30 seconds.    -   (II) Daily activity included each of the following        activities: (1) Standing (B): the subject stood on their feet        for 20 seconds without moving; (2) Sitting down/standing up (C):        the subject sat down and stood up from a chair 4 times,        remaining 3 seconds in each state; (3) Bending down (D): the        subject bent down 3 times, always in the same way (without        flexing their knees); (4) Arm movement (E): the subject moved        their arms in different directions (straight, horizontal and        vertical) 3 times each; and (5) Walking (F): The subject walked        at a approximate speed of 3 km/h for 20 seconds.    -   (III) Strong Physical Activity (H) is defined by: (1)        Moderate-speed Running (I): the subject ran at a speed of 6 km/h        during 20 seconds; (2) Fast-speed Running (J): the subject sped        up his pace until he reached 10 km/h, then he stayed running at        this speed during 15 seconds; (3) Strong arm movement (racket        move) (K): the subject moved his arm strongly simulating hitting        a ball with a racket (with both arms), doing this movement 5        times; (4) Torso turning (L): keeping the feet in the same        position, the subject turned his torso in both directions, 5        times each; (5) Jumping (M): the subject jumped high, he will        run two or three meters and then he will jumped again. He        repeated this movement 5 times.

Strong physical activity was more physically demanding than the dailyactivity. All the exercises done in the resting and daily activitieswere with the strap or shirt put directly onto the subject (no sweat)and all the strong physical activity was done with the strap or shirtworn by the subject where had sweated. When the differentelectrocardiographic signals were obtained with each shirt or strap wereperformed a sort of measures over these signals to evaluate thedifferent technologies. The measures performed on the signals were (foreach exercise of each activity):

Visual Measures

This measure is a direct recognition, just by watching the signal, ofthe quality of the signal acquired in terms of morphology and beatsdetected. This visual recognition is also used to identify what beats(QRS complexes) are recognizable as beats and which of them are toonoisy to be recognized by a cardiologist. A total of 250 beats wereanalyzed for resting and Daily Activity and for Strong Physical Activitya total of 500 beats were analyzed.

Measures Over the Signal

These measures were made on the signal registered in each exercise ofeach activity session. These measures involve manual and automaticanalysis of the recorded signals.

Autocorrelation:

The signal was segmented each 3 seconds with an overlap of 2 secondsbetween blocks and the autocorrelation was done of each block. Thismeasure follows the formula:

${R_{x}(m)} = {\left( {{1/N} - {m}} \right){\sum\limits_{n = 0}^{N - 1}{x_{n}x_{n + m}}}}$

where x is a signal of N samples. Then it's normalized regarding to thevalue of R_(x) (0). Next. the autocorrelation maximum that it's not theone in R_(x norm) (0) is obtained. At this point, it is believed thatthere is a maximum at this point because the signal is compared toitself without shift.

This index give us a measure of how much the signal resembles a shift toitself (starting from the premise that a heartbeat and the next one arevery similar). In this way, values close to 1 show that the signal isvery similar to a shifted copy of itself, so it's clean of noise, whilelow values show that the signal is corrupted by noise.

T-P Segment RMS:

The RMS (Root Mean Square) of the T-P segment was calculated in betweenheartbeats (aprox. 20 segments). This measure was done for each exerciseand, averaged, give an estimate of the noise in the signal, particularlyin Resting state, because the T-P segment is isoelectric.

These measures were done manually (to select the beginning and end ofeach segment). In those signals where the T wave was not present(ZEPHYR™ HxM and Polar TEAM² straps and NUMETREX® Cardio-Shirt inResting and Daily Activity), the segment is defined between twoconsecutive heartbeats. This value has to be as low as possible but hasto be contextualized with the QRS amplitude (see the pointRMS/AmplitudeRS).

Maximum T-P Segment:

It measures the maximum peak of noise of the different T-P segments.This value was useful to see if high peaks of noise contaminate oursignal.

Maximum Amplitudes:

The amplitudes of the QRS peaks were measured (R peaks and S peaks, toget RS amplitude) for the beats of each exercise. There was not apreferred value but higher values tend to be better to low ones (lowones are more prone to noise).

RMS/AmplitudeRS:

This factor was calculated with the measures explained in the previouspoints. This index gives an accurate idea of the noise of the system inthe different exercises. It is normalized to the RS Amplitude becauseeach shirt/strap captures a different amount of signals, differentamplitudes, so RMS in the T-P segment has to be contextualized to eachsensor strap or shirt. In general, a lower value is better.

Of all the index and values obtained, the most important ones areRMS/AmplitudeRS and Autocorrelation because both of them are very goodindicators of the noise that contaminate the signals and howrecognizable are the heartbeats in the registered signals.

The results were divided into and presented as three sections: resultsfor Resting Activity, Daily Activity and Strong Physical Activity.

Resting and Daily Activity

FIG. 6 depicts the amplitude RS (A(v)) in resting (A), stand (B),stand/sit (C), bend (D), arms (E), walk (F), and all the activities,resting, stand stand/sit, bend arms and walk (G) for ZEPHYR™ HxM strap(I), Polar TEAM² strap (II), NUMETREX® Cardio-Shirt (III) and a shirt ofthe invention (IV). The amplitude RS gives an idea of the signalcaptured by the system and it is understood that a high amplitude RS isbetter than a lower one. As depicted in FIG. 6, the shirt of theinvention was able to capture the signal more efficiently and betterthan the other garments. It also worked better in dry conditions as thisactivity session does not involve sweating.

FIG. 7 depicts RMS/Amplitude RS in resting (A), standing (B),standing/sitting (C), bending (D), arms (E), walking (F), and restingand daily activity (resting, standing, standing/sitting, bending armsand walking) (G) for ZEPHYR™ HxM strap (I), Polar TEAM² strap (II),NUMETREX® Cardio-Shirt (III) and the shirt of the invention (IV). Thisdata has value as the noise is contextualized regarding the AmplitudeRS,and it's a good measure of the SNR (Signal-to-Noise Ratio) of thesystem. The value calculated here is Noise-to-Signal, so the lower thisvalue the better. As depicted in FIG. 7, the shirt of the invention (IV)showed the lowest value.

FIG. 8 depicts the percentage of a good QRS complex in resting and dailyactivity for ZEPHYR™ HxM strap (I), Polar TEAM² strap (II), NUMETREX®Cardio-Shirt (III) and the shirt of the invention (IV). FIG. 8 depictshow many beats are recognizable as QRS at first sight. A total of 250beats were analyzed for each system, and the results depict the total ofthe Resting and Daily Activity Session (not divided into exercises). Thehigher the percentage the better. The highest value was found for theshirt of the invention (IV).

FIG. 9 depicts the autocorrelation value for ZEPHYR™ HxM strap (I),Polar TEAM² strap (II), NUMETREX® Cardio-Shirt (III) and the shirt ofthe invention (IV) in walking (F), arms (E), standing (B), bending (D),standing/sitting (C) and resting (A). This information provides a goodindicator of the quality, reproducibility and the similitude between theheartbeats. The closer this value is to 1, the better. The shirt of theinvention had the closest value to 1.

Strong Physical Activity

FIG. 10 depicts the Amplitude RS (A(v)) in mid-speed (H), fast-speed(I), torso-moving (J), racket (K), jumping (L), and all the activities,(mid-speed, fast-speed, torso moving, racket and jumping) (M) ZEPHYR™HxM strap (I), Polar TEAM² strap (II), NUMETREX® Cardio-Shirt (III) andthe shirt of the invention (IV). In Strong Physical Activity, likely asa result of the buildup of sweat on the test subject, the amplitude ofthe signal does not differ greatly between technologies, as the sweathelps the conduction of the electric potentials to the electrode anddecreases the impedance of the skin-electrode interface.

FIG. 11 depicts RMS/Amplitude RS in mid-speed (H), fast-speed (I),torso-moving (J), racket (K), jumping (L), and all the activities,mid-speed, fast-speed, torso moving, racket and jumping (M) for ZEPHYR™HxM strap (I), Polar TEAM² strap (II), NUMETREX® Cardio-Shirt (III) andthe shirt of the invention (IV). Based on the results, it is apparentthat the shirt of the invention had the best results.

FIG. 12 depicts the percentage of a good QRS complex during strongphysical activity for ZEPHYR™ HxM strap (I), Polar TEAM² strap (II),NUMETREX® Cardio-Shirt (III) and the shirt of the invention (IV). Basedon the results of the experiment, the shirt of the invention had thebest results.

FIG. 13 depicts the autocorrelation value for ZEPHYR™ HxM strap (I),Polar TEAM² strap (II), NUMETREX® Cardio-Shirt (III) and the shirt ofthe invention (IV) in mid-speed (H), fast-speed (I), torso-move (J),racket (K) and jump (L). Based on the results, the shirt of theinvention had the best results.

Example 2

The experiment involved a shirt of the invention (IV), wherein the trackand the electrode are made of conductive fabric and the electrode areahas the orifices filled with silicone rubber, and a shirt of theinvention without silicone rubber (V). The protocol followed was thesame as described above comparing a garment of the invention with othergarments by other manufacturers.

FIG. 14 depicts an RMS/Amplitude RS in mid-speed (H), fast-speed (I),torso-moving (J), racket (K), jumping (L), and all the activities,mid-speed, fast-speed, torso moving, racket and jumping (M) for a shirtof the invention (IV) and a shirt of the invention without siliconerubber in the orifices of the electrode area. As depicted, a shirt ofthe invention with silicone in the orifices of the electrode area hadthe best results, as seen by the lower noise and better signal. Inaddition, the shirt with silicone in the electrodes showed betteradherence to the skin.

Example 3

In this experiment, the performance of the fabric of the invention wasmeasured at different levels of stretching to evaluate how thestretching affected the quality of the signal. The fabric in the examplecomprises an electrically conductive area which comprises a conductivesilicone (VP97065/30 from Alpina Technische Produkte GmbH), twoelectrodes of conductive fabric made of conductive fibers andnon-conductive fibers, wherein the conductive fibers are made of silvercoated nylon (X-static® yarns from Laird Sauquoit Industries) andnon-conductive fibers are made of nylon.

To test and evaluate the signals transmitted through the electricallyconductive area (track) comprising conductive silicone VP97065/30, theelectrically conductive area was subjected to different levels ofstretching. Three states were evaluated: resting, electricallyconductive area stretched by about 25% and electrically conductive areastretched by about 50%.

The signal was generated by a PS420 Multiparameter Patient ECG Simulator(from Fluke Corporation) and passed through electrodes, and conductedvia the conductive silicone to an electronic instrument for receivingand transmitting the signal to a computer for visualization and furtheranalysis.

For reference, the Resting state of the electrically conductive areawhere it is not stretched, had a length 6.5 cm. For further reference,25% Stretching increased the length of the electrically conductive areato 8.125 cm and 50% Stretching increased the length of the electricallyconductive area to 9.75 cm. For each state (Resting, 25% and 50%stretching) two segments of signals were captured consisting of 9-10heart beats of the ECG Simulator (10 seconds each segment because thesimulator is configured at 60 beats per minute).

Visual Measures

This measure was determined by watching the signal and evaluating thequality of the signal acquired in terms of morphology and noisedetected. This visual recognition is also used to identify what beats(QRS complexes) and characteristic waves were recognizable and which ofthem are too noisy to be recognized by a cardiologist. A total of 500beats were analyzed for each different level of electrically conductivearea stretching.

Measures Over the Signal

These measures were made on the signal registered in each level ofstretching. These measures involve manual and automatic analysis of therecorded signals.

Cross correlation: the signal was separated between the different levelsof stretching and compared with the correlation between each other. Thecross-correlation was a measure of similarity of two waveforms as afunction of a time-lag applied to one of them. This was relevant as itwas used an ECG Simulator that generated the same beats with nodifference between them. As a result, when a cross-correlation betweentwo signals (one with no stretching and one with stretching) isconducted, the only difference between them will be the noise. Thismeasure goes from 0 (no similarity, completely different) to 1 (thesignals are equal).

RMS Noise: the RMS (Root Mean Square) of the T-P segment was becalculated in between heartbeats. This measure was done for eachstretching level and averaged. The RMS provides an estimate of the noisein the signal. These measures were done manually (to select thebeginning and end of each segment). Both values were very important andvery good estimators of the noise present in the signal and thedistortion introduced by the stretching of the silicone rubber loadedwith electrically conductive material.

Visual Results Obtained Taking Captures of the Signal Directly from theComputer

The line that crosses the ECG strips indicates the point where thestretching started and maintained until the end of the strip.

25% Streching: Two examples, (FIG. 16, FIG. 17), it is seen that theleft part of the strip (left of the line) did not stretch theelectrically conductive area, and the right part of the strip (right ofthe line) did stretch the electrically conductive area.

50% Streching: Two examples, (FIG. 18, FIG. 19), it is seen that theleft part of the strip (left of the line) did not stretch theelectrically conductive area, and the right part of the strip (right ofthe line) did stretch the electrically conductive area.

As depicted in these figure, it is clear that the quality of the signalwas barely affected by the stretching of the electrically conductivearea. While more noise was present and visible when the track wasstretched to 50%, this noise was not sufficient to corrupt the signal.In addition, the waves and characteristic points were still visible andwhat noise existed, was easily filtered in a post processing.

Signal Measures Results: RMS Noise

25% Stretching: The results are given for four different segments, twoof them with the electrically conductive area not stretched (NOSTRETCH_1 and NO STRETCH_2) and the other two with the electricallyconductive areas 25% stretched (25% STRETCHING_1 and 25% STRETCHING_2).

TABLE 1 RMS Noise RMS Noise No Stretch 1 0.11918993 25% Streching 10.13268027 No Stretch 2 0.14075932 25% Streching 2 0.14376695

In both cases, the signal without stretching the electrically conductiveareas had less noise than when the electrically conductive area wasstretched after that. This is further found when looking at the averageRMS Noise results in Table 2.

TABLE 2 Average RMS Noise RMS Noise No Stretch 0.12997463 25% Streching0.13822361

50% Stretching: The results are given for four different segments, twoof them with the electrically conductive area not stretched (NOSTRETCH_1 and NO STRETCH_2) and the other two with the electricallyconductive area 50% stretched (50% STRETCHING_1 and 50% STRETCHING_2).

TABLE 3 RMS Noise RMS Noise No Stretch 1 0.14470239 50% Streching 10.14615933 No Stretch 2 0.14576144 50% Streching 2 0.15123728

In both cases, the signal without stretching the electrically conductivearea had less noise than when the electrically conductive area wasstretched after that. This is further found when looking at the averageRMS Noise results in Table 2.

TABLE 4 Average RMS Noise RMS Noise No Stretch 0.14523191 50% Streching0.1486983

As the difference between the two states was not significant, it isapparent that very little noise was present due to the stretching of theelectrically conductive area.

Cross Correlation

Table 5 shows the results for the 25% Stretching and 50% Stretching.

TABLE 5 Cross Correlation Cross Correlation No Stretch/25% Strech0.975041781 No Stretch/50% Strech 0.960290

As seen in Table 5, the signal was barely corrupted by noise in eithersituation. Though the 50% stretching was a little worse than that of the25% stretching, the difference in the results was not significant asthey differed by only 4%.

Example 4

In this example, a comparative test between an elastic semi-conductivetrack directly in contact with a rigid electrical connector (Assembly 1)and the elastic semi-conductive track and flexible conductive supportbase assembly of the invention wherein the rigid electrical connector isin contact with the support base (Assembly 2) was conducted.

Assemblies where prepared with elastic semi-conductive track made withthe conductive silicone rubber loaded with carbon black, VP97065/30(Alpina Technische Produkte GmbH); Assembly 2 included a flexiblesupport base which was prepared with a conductive textile made withconductive fibres of silver coated nylon commercialized as X-STATIC®(Laird Sauquoit Industries), and non-conductive fibres of nylon; whereasthe substrate in both assemblies was made with polyester, nylon andLYCRA® fibres.

The tracks were 80 mm long and 15 mm wide. Tests were repeated 3 times.Resistivity between both extremes of the track was measured in order toevaluate the durability of the assembly. Resistivity increases withelongations of material, in case of a break the resistivity isdrastically increased. Generally, resistency values should not exceed 25kΩ. Each test consisted of applying three cycles of different lengths ofstretching. The first cycle of 30 repetitions subjected specimens to140% elongation (Table 6).
